In the dozen years since Polhemus Savery DaSilva Architects Builders was formed in Chatham, Massachusetts, the firm created a significant body of wooden buildings that are rooted in the seaside vernacular of Cape Cod, Martha's Vineyard, and Nantucket—the shingle style that historian Vincent Scully called the "architecture of the American summer." Yet each of the 32 projects here, seen in page-filling color photos and drawings, was approached as an individual work of art and craft associated with the client and the site.
